Measuring the Quality of Treatment and Outcomes for Patients with Aneurysms at the Cedars-Sinai Department of Neurosurgery
A brain aneurysm is an abnormal bulging of one of the arteries in the brain. Aneurysms are classified as ruptured or unruptured and are treated by a clipping or coiling procedure. Clipping is a surgical procedure in which a clip is placed across the neck of the aneurysm to stop or prevent an aneurysm from bleeding. Coiling is a minimally invasive endovascular procedure; during coiling, tiny coils are packed into the aneurysm to promote blood clotting and close off the aneurysm.
As part of its ongoing focus on continually improving the care given to patients with aneurysms, the Cedars-Sinai Department of Neurosurgery monitors:
- The volume of aneurysms treated at Cedars-Sinai
- Mortality rates for patients who underwent the clipping or coiling procedure for ruptured or unruptured aneurysms before after discharge from Cedars-Sinai Medical Center
- Length of stay for patients who underwent the clipping or coiling procedure for ruptured or ruptured aneurysms before discharge from Cedars-Sinai.
The data shown in the graphs below comes from the University HealthSystem Consortium (UHC), an alliance of more than 300 of the nation’s non-profit academic medical centers and their affiliated hospitals. The majority of these facilities participate in UHC's Clinical DataBase/Resource Manager. The data were accessed on May 23, 2016 based on patients discharged between January 1, 2013 through December 31, 2015.
Volume of Aneurysms Treated at the Cedars-Sinai Department of Neurosurgery
The graph below shows the total number of ruptured and unruptured aneurysm repairs performed annually at Cedars-Sinai, using both clipped and coiled procedures. Many patients have multiple aneurysms repaired at a time.
The observed percent mortality is the actual number of patients that expired in the hospital divided by the total number of patients who had the same procedure. The expected percent mortality is the number of patients anticipated to expire divided by the total number of patients who had similar diagnosis, procedure, age, gender and complications. The graph below illustrates the difference between the observed percent mortality and the expected percent mortality of coiled patients that expired by year.
A lower observed mortality rate is better than a higher one.
Length of Stay
The graph below compares the actual (or observed) length of stay for patients hospitalized at Cedars-Sinai Medical Center compared to what would have been expected from patients of similar gender and age who had similar diagnoses, procedures and complications.
